I have a button with onclick function. It passes a variable $x into the java script. Shortly what i want to do is to pass the $x="aaa" to the javascript, and make the function to change this variable into lets say $x="bbb" without refreshing the website. So i would be able to click it all the time and the js could change the value of given variable. I mean the content variable going from button to javascript would be changed depending on js function code. This may sound complicated i am really sorry for that. Any ideas? (the code below i just made up because it would be to long to explain here all my code that is very long now)
<?php x = "aaa"; ?>
<button onClick="someFunction(<?php $x ?>)"></button>
<script>
function someFunction (x){
//what can i do here to make this "aaa" string in variable change
//into for example "bbb" on clicking it again?
}
</script>
